? Firewall gauge connection harness

I am getting ready to replace that 50 year old under the hood harness and wanted to check to make sure, does that harness simply pull off of the firewall and the new one just plug back in? Use dielectric grease?

I just don't want to be tugging on it and creating a new problem.

There are 3 or 4 small metal tabs that lock the inside harness to the firewall- they're on the engine side. The engine side just pulls off, then you can push the tabs inward with a flat blade screwdriver and push the plug through and into the cab. The new one should be the reverse- it'll lock into place when you push it through from the inside...


ok- just reread your post- yes, the engine side just pulls off... sorry for the extra detail..
